A camera system for use with retractors. The system includes a camera assembly configured for mounting on the proximal end of a retractor system. The camera assembly viewing axis may be translated between a first and second position to obtain a stereographic image pair, and a control system is operable to control the camera assembly and an associated display to present the stereographic image pair as a wigglegram which conveys 3D information to the user.

Wigglegram camera system for use with retractors

A cannula system and method for accessing a blood mass in the brain. The system comprises a cannula with a camera mounted on the proximal end of the cannula with a view into the cannula lumen and the surgical field below the lumen. A prism, reflector or other suitable optical element is oriented between the camera and the lumen of the cannula to afford the camera a view into the cannula while minimizing obstruction of the lumen. The system may also include an obturator with a small diameter shaft and a large diameter tip which is optically transmissive, so that a surgeon inserting or manipulating the assembly can easily see that the obturator tip is near brain tissue (which is white) or blood (which is red).

Cannula with proximally mounted camera and transparent obturator

A retractor, distractor, and camera system with the camera system and/or distractor configured to provide releasable attachment of the camera system to the distractor, and also provide for rotation of the camera assembly relative to the distractor to allow for adjusting the aim of the camera viewing axis to obtain an image of the surgical workspace established by the retractor.

Retractor, distractor, and camera system for cervical procedures

A cannula suitable for use in minimally invasive surgery is improved with a highly polished and very smooth luminal wall and/or LED's or other light sources focused at particular angles relative to the axis of the cannula. The devices provide for improved lighting and/or reduced lighting requirements for cannulas used for minimally invasive surgery.

Lighted cannula system

An anchoring system for cannulas or tools to be inserted into a surgical workspace in the body, particularly the brain, of a patient. The system comprises a mounting ring which may be fixed to the skull to both secure the system to the skull and protect the skull opening from passage of cannulas and tools, a resilient clip with grasping jaws adapted to firmly grasp a cannula or tool, and a flexible membrane secured to the outer rim of the mounting ring and the clip.

Anchoring system and method for cranial access

A camera and expandable bladed retractor system. The system includes a camera, with a distal-most optical element disposed over the proximal end of the lumen or surgical channel established by the retractor blades. The camera may be fixed to the retractor, either to the proximal end of a blade or to a frame member.

Devices and method for access and visualization for lumbar interbody fusion (LIF)

A macerating and aspiration tool for removing blood masses from the brain.

Macerating and aspiration tool for intracranial surgery

A camera system for use with retractors. The system includes a camera assembly configured for mounting on the proximal end of a retractor system, such as the proximal end of a blade such that the entirety of the camera assembly is disposed at the proximal end of the retractor system may be disposed such that the distal-most optical element overhangs the working channel established by the retractor, and includes a reflector and a rotatable mount for the reflector, camera assembly viewing axis may be altered without changing the position of the entire camera assembly.

Camera system for use with retractors

An anchoring system for cannulas or tools to be inserted into a surgical workspace in the body, particularly the brain, of a patient. The system comprises a grommet which may be fixed to the skull to both secure the system to the skull and protect the skull opening from passage of cannulas and tools, a resilient clip with grasping jaws adapted to firmly grasp a cannula or tool, and a flexible membrane secured to the outer rim of the grommet and the clip.
